SINKER FOR KNITTING MACHINES Filed Deo. 8. 1952 HARQLP E.. STC uf,

NVENTOR BY k ATTOR N EY Patented Feb. 27, 1934 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to new and useful improveinents in sinkers for knitting machines.

It is the object of my invention to provide a sinker so constructed that the rivets, lugs or oth- 5 er means by which its constituent parts are held together, will not be jarred loose during the use of the sinker.

With this object in View I provide a special striking surface on the back edge of the sinker 0 so as to relieve the strain under which the rivets, lugs or the like may be placed. The striking surface is preferably constituted by a bent-over ledge of one or both side plates so arranged that all striking strains caused by the jacks are absorbed by one of the side plates and the blade rather than by the rivets, lugs or the like.

In order more clearly to explain the details of my invention, I shall describe them in connection with the drawing in which:-

Fig. l is a sectional View of a sinker having lugs formed out of one of the side plates in accordance with my Patent No. 1,784,256;

Fig. 2 is a sectional view of a sinker using separate rivets;

Fig. 3 is a side elevation of a sinker having la modified form of a reenforcing arrangement;

Fig. 4 is an end view of Fig. 3;

Fig. 5 is a perspective View of the sinker shown in Fig. l; and

Fig. 6 is a perspective View of a modified construction.

In Fig. 1 an L-shaped side plate 1, a blade 2 and a second L-shaped side plate 3 are held together by means of lugs formed in side plate l. The back edge 4 of side plate 3 is bent over to provide a solid one-piece striking surface for the jacks. This striking surface willrelieve the lugs of all strains.

In Fig. 2 a side plate 5, blade 6 and a second side plate '7 are held together by means of separate rivets like 9 which are protected from strains by the bent-over ledge 8 of side plate 7.

In the arrangement shown in Figs. 3 and e, the side plate 12 has two bent-over ledges 13 and 14, aifording not only a striking surface for the jacks, but also a means of aligning the side plate 12, blade 10 and the second side plate 1l and a one-piece surface for the return of the sinker by the catch bar of the knitting machine.

In Fig. 6 a modilication of the structure illustrated in Figs. 1 and 5 is illustrated in which the striking surface is constituted by a bent-over ledge 4 of side plate 3 and a bent-over ledge da of side plate 1 below the ledge 4.

What is claimed is:

1. In a sinker for knitting machines, two side plates, a. blade held between said side plates, and a striking surface overlying and contacting with the backs of the blade and at least one of the 0 side plates.

2. In a sinker for knitting machines, two side plates, a blade held between said side plates, and a bent-over ledge formed in one of the side plates contacting with the backs of the blade and the other side plate and affording a striking surface for the jacks.

3. In a sinker for knitting machines, two side plates, a blade, rivets passing through said blade and said side plates, and a bent-over ledge formed in one of the side plates contacting with the backs of the blade andthe other side plate and affording a striking surface for the jacks.

4. In a sinker for knitting machines, a rst and a second side plate, a blade held between said plates, a bent-over ledge in the first side plate contacting with the backs of the blade and the second side plate, a bent-over ledge in the second side plate contacting with the blade and the first side plate, said bent-over ledges affording a striking surface for the jacks.

5. In a sinker for knitting machines, a first and a second side plate, a blade held between said plates, a bent-over ledge in the first side plate contacting with the backs of the blade and the second side plate, a bent-over ledge in the second side plate contacting with the blade and the first side plate below the first mentioned ledge, said bent-over ledges affording a striking surface for the jacks.

6. In a sinker for knitting machines, two side plates, a blade held between said plates, a bentover ledge formed in one of the side plates and contacting with the backs of the blade and the other side plate and constituting a striking surface for the jacks, and a second bent-over ledge in said one of said side'plates contacting with the front edge of said other side plate and constituting with the first mentioned ledge a means for aligning the two side plates.

'7. In a sinker for knitting machines, a first and a second substantially L-shaped side plate, a blade held between one leg of said plates, a bent-over ledge formed in the other leg of the first side plate and contacting with the backs of the blade and the other leg of the second side plate and constituting a striking surface for the jacks, and a second bent-over ledge in said other leg of said first side plate contacting with the front edge of the other leg of said second side plate and constituting with the first mentioned ledge a means for aligning the two side plates, and a one-piece surface for the return of the sinker by the catch bar of the knitting machine.
